The compressive strength of sandcrete blocks is affected by the mix proportion, quality of material used in making them, size, shape, and the mode of manufacture (i.e. hand or machine mould). Physical conditions such as method and days of curing, duration of time, temperature etc will also contribute to the strength of the block (Dhir, 1980).

2020-12-31 Sandcrete Blocks (NIS 87 [1]), which provides a guide for producing sandcrete blocks of acceptable quality. This standard describes different types and classes of sandcrete in terms of shapes, sizes, and compressive strength. The lowest strength class requirements are 2.5 N/mm2 and 3.45 N/mm2 for individuals and a minimum of five blocks, respectively.

Nevertheless, the compressive strength of the sandcrete blocks themselves was below the standard recommended by Nigerian Industrial Standard (NIS) 87: 2000. The compressive strength of individual blocks was between 0.11 N/mm 2 and 0.75 N/mm 2 , and the average compressive strength of the blocks were between 0.14 N/mm 2 and 0.66 N/mm 2 .

2019-10-2 The compressive strength of sandcrete block is a very important aspect of a block in a building. In many cases of building failures in Nigeria, the strength of the sandcrete block, has been figured as one of the causes of the failure. For this reason, in this research, some blocks were purchased from seven block producing industries in Kaduna ...
